Here are the basics of one way to build a mini-module. This one is made from parts purchased from a company that makes model railroad layout frames and legs. You could make your own.



The important thing is that the dimensions have to be as follows:
Length or depth: 36" (plus or minus 1/16")
Depth or length: 18" (plus or minus 1/16")
Distance from the top of the rails to the floor: 40" (with 1" up and 1" down adjusters)


Other requirements:
Two mainlines, code 83 track:
Eastbound: 4" on center from the front edge
Westbound" 6" on center from the front edge


Electrical wiring and connections:
Follow the specs for the club's regular modules.
Wiring colors (starting from closest to the visitors' side of the module): Orange (eastbound +)
White (eastbound -)
Blue (westbound -)
Red (westbound +)
Green (siding -)*
Yellow (siding +)*

*Siding is not required. If used, follow the colors shown. Wiring for other trackage can be any color not shown above.


Mini-module specs — subject to change.
